Powers/Abilities: Demon is incredibly agile and one of the best martial
artists in the world.

History: A member of Georwell's Justice Machine, Demon was obsessed
with being the best. However, he found that he could never outdo his commanding
officer, Challenger, in spite of being several years younger, so he began
to covertly take performance enhancing drugs. After the Justice Machine became
fugitives and fled to Earth, Demon found it increasingly difficult to hide
his addiction. Eventually he confronted his problem, refusing to be controlled
by it; he fled from his teammates, and was believed to have drowned while
swimming from their island base, but eventually returned, clean of the drugs
and back at the top of his game.
